On the outer surface of the bolt i there is a projection 36, which, when the bolt is pushed in, is pressed behind one of the cogs 23. In this way the cover i2 is locked and the cartridge feeder H can press the row of cartridges forward.

In 1 the cartridge channels 3 and ti are filled with cartridges. Below an outlet 3'! in the wall of the cylinder I there is, a cartridge lifter 29 shaped like a fork. When the cartridges are gliding against it, they rise up into the outlet.

The outer cartridge channel 3 is, as mentioned above, formed by the wall of the cylinder l and by the plate cylinder 2 the washer 2 acting as the base of the channel. The one end of the plate cylinder 2 almost touches the wall of the cylinder I, the other ending at the projection 30. This projection has been made so wide that it just fits in between the arms of the cartridge lifter 29.

' When the cartridge feeding has proceeded so far that the channel 3 is empty, the projection 30 has been pressed between the arms of the cartridge lifter 29; and the mouth of the channel a has come to the outlet 37.

Behind the fork 29 there is a shoulder 3! the purpose of which is to stop the projection 36 when it has gone past the cartridge lifter 29. In this way is also the end 2" of the plate cylinder 2 prevented from revolving forward.

When filling the case, remove the cover l of the case in such a way that the end 23 of the bolt is pressed inwards and then the cog 23 in the head 9 of the boltgoes past the projection 36 in the latch I. Now the latch i can be turned away. When the latch i is opened, the cover of the case can be lifted off and the spring a l presses the head 9 of the bolt against the cover ii of the spring case 6.

After this the spring of the case is compressed by seizing with the fingertips the projections i2- and turning to the left'as far as possible.

After this the case is filled in such a way that the cartridges are put into the cartridge channels 3 and d with their bases against the washer 2, after which the cover of the case is closed in the way described above, and the case is ready for firing.

When firing the spring '7 makes the spring case 6 and at the same time the washer 2 rotate by means of the feeder ii and the cartridges of the cartridge channel 6. When the cartridges, as described, go through the outlet 31, the washer 2 rotates under the influence of the spring 1 until the cartridges in the channel 3 are all gone, and the projection 30comes against the shoulder 31 (the case is now acting as a drum case) and the shoulder 8! has such a position that the end of the channel a comes to the outlet 31. When the washer 2 can no longer rotate but the spring '5 is pressing the cartridges with the feeder I l, the cartridges in the channel t go off through the outlet 31 in the same manner as in the rod cases.
